Magnetic Holder for flying extruder

thingiverse

With the flying extruder the effector is to heavy for the belt with stepper motors turned off. So I designed a arm with one or two 14 mm Magnets on the Top that fixes the extruder in the upper position, but can release with little force when the printer starts printing. Because the arm is 5 mm longer than needed (to be sure that it klicks to the top) before shutting of the stepper set a G-Code to "G0 X0 Y0 Z210" (for my FLSun Q5 , generally around 4-5mm below the G28 upper point, so that after shutting of the Stepper it does not 'fall' into the holder. It also have a filament guide arm if you need it. Wheight: around 5g!
